Considering the future of the oceans

In the concluding installment of our two-part season finale of
Naked Oceans, we get a bit thoughtful and contemplate what might
lie in store for the future of the oceans. Helen catches up with
some of the marine experts we've heard from throughout the last two
series and asks them about what they think the future might hold.
Are they ocean optimists or pessimists? What solutions will be
needed to protect the oceans of the future? And on a more positive
note, we ponder what great ocean discoveries might lie ahead. For
